So I’ve noticed a lot that when in GPS Hold:On mode that if I move in a single direction for a period of time (4-5 seconds) especially really fast, that when I let go of the stick that it’ll continue to drift in that direction.
Additionally, if I let go of the stick and yaw, it’ll continue drifting in the same direction it was going. This seems like a Kalman Filtering thing. In my time with aircraft KFs, if you did a specific maneuver for a “long time” then some of that tended to translate into KF drifting. Scaled up, long time was in minutes. For example if an aircraft orbits for a long time, it’ll will throw the CEP way out. My expected performance with a EKF (GPS stamped KF) is when I let off the stick that it’ll (relatively) quickly come to a stop and try to hold the position where it came to a stop. Instead, I find myself having to fight it to stay in position for a few seconds manually, before it’ll correctly stay in that position. Has anyone else seen this? Is this the expected performance?
